Gold Goombas also appear in New Super Mario Bros. 2. However, they are simply regular Goombas after Mario or Luigi touch a Gold Ring. The player will get 5 coins for each enemy defeated. The same applies to other gold enemies (this does not include consecutive jumps on enemies or using the Gold Flower).

As enemies, Gold Goombas first use their Skill Super Boost to raise the attack power of all enemies for 99 turns. They then attack regularly by charging and slamming into the player (making metallic clanking noises). When defeated, they drop Grand Light Blocks of themselves or Star Gems. When defeated with a 10+ Combo attack, they are guaranteed to drop Star Gems. Gold Goombas award the player with a significant amount of XP compared to other enemies, but drop a regular amount of coins.

As teammates, Gold Goombas have above average stats, with an HP rating of 5/6, an ATK rating of 4/6, and a RCV rating of 4/6. Its Super Boost Skill changes one Orb on the Orb field to a Super Orb, and its Awoken Skill, Time Boost, increases the time the player can move Orbs by a short amount. Gold Goombas give HP+ bonuses to other teammates when being depowered, and use Gold Mushrooms and Grand Gold Mushrooms to increase their Skill levels.

With the digital update to version 2.0, a Gold Goomba can be transformed into two other forms: a Gold 2-Goomba Tower by using four Goomba Coins, and a Gold 3-Goomba Tower by using six more Goomba Coins.

In Super Mario Run, Gold Goombas appeared during a "Mega Event" running from January 31, 2017 to February 19, 2017. They were found in World Tour in certain levels at a time (indicated by a Gold Goomba icon on the level selection screen), with stages containing anywhere from one to five Gold Goombas (the later stages feature more Gold Goombas than the earlier ones). The player received 30 bonus coins at the end of the level for every Gold Goomba stomped, as well as a stamp on their stamp card, which was given to players as part of the event. If the player got 20 stamps and completes the stamp card, they could receive a Gold Goomba Statue, which can be used in Kingdom Builder. If the player completed three more stamp cards, they could receive two Gold Goomba Statues, three Gold Goomba Statues, and a Big Gold Goomba Statue, respectively.[3]

Gold Goombas appeared in another "Mega Event" running from March 30, 2017 to April 13, 2017. The event was identical to the last Mega Event, except the prizes were a Dandelion, Piranha Plant Statue, Dandelion Trio (three individual Dandelions), and a Cherry Blossom Tree. The event returned again on August 10, 2017, and will end on August 31, 2017.
